with regard to whether it wishes to offer the proposed vendor financing. The
Owner's Notice shall provide reasonable specificity to enable Vendor to evaluate
the Owner's Notice. Owner further agrees to reasonably cooperate with Vendor by
providing any non-confidential information reasonably requested by Vendor for
purposes of verifying the information contained in Owner's Notice.

available to Owner from its Primary Vendor as of the date of Owner's Notice.
The parties agree to use commercially reasonable efforts to cause the
determination of Vendor's infrastructure prices versus the infrastructure prices
of the Primary Vendor to be based on an "apples-to-apples" comparison (taking
into consideration not only the pricing of products and services, the cost to
obtain, install, maintain and operate the system, and the terms and conditions
of any other material consideration proposed to be given or received by any
competing bidder, including the financing terms and conditions and each of the
Competitive Factors).

1A.9 Vendor Preference. Provided that Vendor has: (i) given a timely Vendor's
-----------------
First Notice; (ii) not terminated this Contract pursuant to a Vendor's Second
Notice, and has complied with all of the requirements of subsection 1A.3; and
(iii) satisfied the conditions of subsections 1A.4 through 1A.8 above, Owner
shall purchase from Vendor Products and Services for the next Available Market
deployed by Owner or its Affiliates after the Delivery Date (the "Test Market").
-----------
The System deployed in the Test Market shall be subject to a "soak" period,
during which it will be operated for [*] after the Substantial Completion date
in order to determine whether it is operating in accordance with this Contract
and the Specifications (the "Test Period"). If a Major Outage occurs at any
-----------
time during the last [*] of the Test Period, then the Test Period shall be
extended until the date on which the System has operated for [*] consecutive [*]
after the cause of the latest Major Outage

has been corrected to the reasonable satisfaction of the Owner and Vendor. For
the Test Market, the Initial Period, defined in subsection 10(f), shall be
extended until the last day of the Test Period, as extended from time to time
pursuant to the terms of this subsection. For the Test Market, Final Acceptance
shall not occur until the successful completion of the Test Period. Provided the
System in the Test Market has successfully completed the Test Period and reached
Final Acceptance prior to September 20, 2002, and Vendor has otherwise complied
with the terms of this Contract, Owner shall purchase during the Contract Term
from Vendor additional Products and Services for deployment in its remaining
Available Markets in accordance with the following: (i) if as of the expiration
of the Test Period the projected cost (as reasonably set forth in Owner's
business plan) to deploy Products and Services in all of the remaining Available
Markets is equal to or greater than $330,000,000 (less the price of the Products
and Services previously deployed in the Test Market), then Owner agrees to
purchase, during the Contract Term, a minimum of $330,000,000 (less the price of
Products and Services previously deployed in the Test Market) of Products and
Services for deployment in such remaining Available Markets; or (ii) if as of
the expiration of the Test Period the projected cost (as reasonably set forth in
Owner's business plan) to deploy Products and Services in all of the remaining
Available Markets is less than $330,000,000 (less the price of the Products and
Services previously deployed in the Test Market), then Owner shall purchase from
Vendor during the Contract Term all of its Products and Services requirements
for the remaining Available Markets until such time as Owner has purchased from
Vendor Products and Services up to an aggregate total cost of $330,000,000 (less
the price of the Products and Services previously deployed in the Test Market).
If the System in the Test Market fails to reach Final Acceptance or fails to
successfully complete the Test Period in accordance with the Specifications and
this Contract prior to September 20, 2002, then Owner shall have the option to
terminate this Contract without any further liability to Owner. Owner agrees
that it will deploy its Products and Services in good faith and in a
commercially reasonable manner and that it will not arrange the deployment
schedule so as to deploy Products and Services in the Contiguous Markets where
the purpose is to delay the deployment of Vendor's Products and Services in the
Test Market.

any Defects or Deficiencies or Defective Work; or (v) in any way release the
Vendor from being solely responsible to the Owner for the Work to be performed
under this Contract.

4.2 Vendor's Liability. The Vendor is responsible for all of its
------------------
obligations under this Contract, including the Work, regardless of whether a
subcontract or supply agreement is made or whether the Vendor relies upon any
Subcontractor to any extent. The Vendor's use of Subcontractors for any of the
Work shall in no way increase the Vendor's rights or diminish the Vendor's
liabilities to the Owner with respect to this Contract, and in all events,
except as otherwise expressly provided for herein, the Vendor's rights and
liabilities hereunder with respect to the Owner shall be as though the Vendor
had itself performed such Work. The Vendor shall be liable for any delays
caused by any Subcontractor as if such delays were caused by the Vendor.

4.3 No Effect of Inconsistent Terms in Subcontracts. The terms of
-----------------------------------------------
this Contract shall in all events be binding upon the Vendor regardless of and
without regard to the existence of any inconsistent terms in any agreement
between the Vendor and any Subcontractor whether or not and without regard to
the fact that the Owner may have directly and/or indirectly had notice of any
such inconsistent term.

4.4 Assignability of Subcontracts to Owner. Vendor shall use
--------------------------------------
reasonable efforts to have each agreement between the Vendor and a Subcontractor
contain a provision stating that, in the event that the Vendor is terminated for
cause, convenience, abandonment of this Contract or otherwise then: (i) each
Subcontractor shall continue its portion of the Work as may be requested by the
Owner; and (ii) such agreement permits assignment thereof without penalty to the
Owner and, in order to create security interests, to third parties designated by
Owner, in either case at the option of the Owner and for the same price and
under the same terms and conditions as originally specified in such
Subcontractor's agreement with the Vendor.

4.5 Removal of Subcontractor or Subcontractor's Personnel. The Owner
-----------------------------------------------------
has the right at any time to request removal of a Subcontractor and/or any of a
Subcontractor's personnel from Work on the System upon reasonable grounds and
reasonable prior notice to Vendor. Such request (a "Request for Removal") shall
-------------------
be in writing and shall specify the Owner's reasoning therefor. The Vendor
promptly shall issue a written response to any such Request for Removal,
specifying the reasoning for its disagreement or agreement, as the case may be,
with the reasoning contained in the Request for Removal. If the parties fail to
agree, this matter shall be handled in accordance with the dispute resolution
procedures in Section 23. The exercise of such right by the Owner shall have no
effect on the provisions of subsections 4.1 and 4.2.

4.6 Subcontractor Insurance. The Vendor shall require its
-----------------------
Subcontractors to obtain, maintain and keep in force, during the time they are
engaged in providing Products and Services hereunder, insurance coverage of the
types and levels customary in the industry (provided that the maintenance of any
-------- ----
such Subcontractor insurance shall not relieve the Vendor of its other
obligations pursuant to this Contract). The Vendor shall, upon the Owner's
request, furnish the Owner with evidence of such insurance in form and substance
reasonably satisfactory to the Owner.

4.7 Review and Approval not Relief of Vendor Liability. No
--------------------------------------------------
inspection, review or approval by the Owner permitted under this Contract of any
portion of the Work shall relieve the Vendor of any duties, liabilities or
obligations under this Contract, but nothing contained in this subsection shall
be deemed a bar of any waiver given by the Owner to the Vendor pursuant to and
in accordance with the terms of this Contract.

4.8 Vendor Warranties. Except as otherwise expressly provided in
-----------------
Section 18, the warranties of the Vendor pursuant to Section 18 shall be deemed
to apply to all Work performed by any Subcontractor as though the Vendor had
itself performed such Work and to all Products supplied by any third-party
vendor or other subcontractor as though the Vendor itself had supplied such
Products. Except as otherwise specifically provided in Section 18, the parties
agree that such warranties shall not be enforceable merely on a "pass-through"
basis but that Owner may, but shall not be obligated to, enforce such warranties
of any Subcontractor to the extent that the Owner determines that the Vendor is
not paying and/or performing its warranties; provided that any such election by
-------- ----
the Owner shall not relieve the Vendor from any obligations or liability with
respect to any such warranty.

4.9 Payment of Subcontractors. The Vendor shall make all payments it
-------------------------
is contractually required to make to all Subcontractors (except in the case of
legitimate disputes

between the Vendor and any such Subcontractor arising out of the agreement
between the Vendor and such Subcontractor) in accordance with the respective
agreements between the Vendor and its Subcontractors such that no Subcontractor
shall be in a position to enforce any liens and/or other rights against the
Owner, the System, any Products or any part thereof.

4.10 Copies. Subject to any confidentiality obligations insisted
------
upon by third party providers, including Subcontractors, Vendor will use its
good faith and reasonable efforts to provide Owner with any and all relevant
agreements, understandings, subcontracts and other documents pertaining to the
provision of Products or Services by a Subcontractor which Owner may reasonably
require in order for it to be provided with the information necessary to
exercise any of its rights under this Contract.

4.11 Benefit of Subcontracts. In addition to anything else provided
-----------------------
for in this Contract, the Owner shall be entitled to the following benefits and
rights of the Vendor under its contracts with any applicable third-party vendors
or other Subcontractors: all rights to conduct in-house tests, to receive
notice of upgrades and enhancements, and to purchase spare parts; provided
--------
however, that the Vendor shall maintain sole responsibility for all obligations
- -------
and other duties under all such contracts.

-------------------
Owner may, in its sole discretion, decide to place a System which is subject to
such delay into In Revenue Service. Such placement into In Revenue Service
shall constitute Substantial Completion only for purposes of the payment
obligations above, but shall not in any way relieve the Vendor of any of its
obligations under this Contract, including without limitation achieving a
Guaranteed Substantial Completion Date nor shall such In Revenue Service trigger
the commencement of the Initial Period.

abuse by other than Vendor; (iii) Products being used in a manner not in
accordance with operating instructions or in a suitable installation environment
or operations of other equipment in the frequency ranges reserved for Owner
within the applicable licensed area. Vendor assumes no responsibility under
this clause for items not specified or supplied by Vendor. The foregoing
warranties are collectively referred to as the "Compliance Warranty".
-------------------

Vendor shall, when appropriate, have reasonable access to Owner's Premises
during normal business hours and at such other times as may be agreed upon by
the parties in order to enable Vendor to perform its obligations under this
Contract. Vendor shall coordinate such access with Owner's designated
representative prior to visiting such premises. Vendor agrees to instruct its
employees to comply with all site rules while on Owner's Premises. The
employees and agents of Vendor shall, while on the Owner's Premises, comply with
all site rules and guidelines including but not limited to where required by
government regulations, submission of satisfactory clearance from U.S.
Department of Defense and other governmental authorities concerned. Neither
party shall require waivers or releases of any personal rights from
representatives of the other in connection with visits to its premises, and no
such releases or waivers shall be pleaded by either party in any action or
proceeding.

For purposes of this Section, all references to "Owner's Premises" and
----------------
other similar references shall be deemed to refer to any location where a Site
is to be located, which may include land or buildings owned or leased by Owner.
To the extent that Owner does not own the premises, Vendor's obligations to
adhere to site rules and guidelines shall include, without limitation, those

document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

submission of a Change Order by the Owner to the Vendor, the matter shall then
be referred to dispute resolution pursuant to Section 23. Nothing contained in
this subsection is intended to limit the Vendor's right, from time to time, to
make suggestions for modifications to the Work or the Specifications, provided
--------
that in any such event the Owner, in its sole and absolute discretion pursuant
- ----
to the terms of this Contract may refuse to make any such modification or
otherwise agree to issue a Change Order incorporating any such Vendor
suggestion.

agrees to provide the Owner, or its Affiliates as the case may be, not less than
one (1) year notice before the Vendor discontinues a Product ("Discontinued
------------
Products") furnished under this Contract. With respect to Products manufactured
- --------
by a third party vendor, the notice period may vary. Where the Vendor offers a
product for sale that is equivalent in Form, Fit and Function in accordance with
and pursuant to the Specifications, the notification period may vary but in no
event shall be less than sixty (60) days. In the event of the foregoing, the
Vendor shall continue to furnish Products fully compatible with the relevant
System Elements within the System at such time during the appropriate [*] and
[*] periods referenced above; provided that nothing herein shall bar the Vendor
-------- ----
from discontinuing individual items of Products as provided in and pursuant to
this subsection. In the event that Vendor discontinues a Product, Vendor will
meet with Owner and use reasonable, good faith efforts to develop a mutually
acceptable transition plan that takes into account the Owner's existing
investment in the item scheduled for discontinuance.

In addition to repairs provided for under any applicable Warranty, Vendor
shall offer repair Services and repair parts in accordance with Vendor's repair
and repair parts practices and terms and conditions then in effect, for Vendor-
manufactured Equipment furnished pursuant to this Contract. Such repair
Services and repair parts shall be available while Vendor is manufacturing or
stocking such Products or repair parts, but in no event less than [*] for the
AXE switch and [*] for all other Products after such Product's discontinued
availability effective date. Vendor may use either the same or functionally
equivalent products or parts which are new, remanufactured, reconditioned or
refurbished in the furnishing of repairs or replacements under this Contract.

If during the agreed-to support period following the issuance of notice of
discontinuance, Vendor fails to provide repair parts and or repair Services and
a functionally equivalent replacement has not been designated, Vendor shall so
advise Owner, to allow Owner to plan appropriately, and if Vendor is unable to
identify another source of supply for such repair parts or services, Vendor
shall, in addition to any other right or remedy available to Owner at law or in

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

equity, provide Owner, at no additional charge to Owner, upon request, with non-
exclusive licenses for Product manufacturing to the extent Vendor can grant such
licenses, so that Owner will have sufficient information, ability and rights to
have such Discontinued Products manufactured, or obtain such repair Service or
repair parts from other sources. Such license shall include appropriate non-
disclosure and confidentiality covenants.

12.2 Discontinuation During Warranty Period. If Vendor discontinues
--------------------------------------
the availability of a Product during that Product's Warranty Period and Owner is
required to purchase a replacement Product to replace the Discontinued Product
in order to maintain the same functionality of the Discontinued Product in a
System, Vendor agrees to grant Owner an additional [*] discount to be applied
against the net price of all Products required to be purchased by Owner as
replacements for such Discontinued Product, which additional discount shall be
applied after the determination of the lowest price available to Owner pursuant
to this Contract.

SECTION 13. SOFTWARE; CONFIDENTIAL INFORMATION

13.1 RTU License. Upon delivery of the Software, but subject to
-----------
payment of the license fees specified in Exhibit B, the Owner is hereby granted
a personal, non-exclusive, fully paid-up, multi-site (capability to move
Software from site to site on prior notice to Vendor) right to use license for
the Software ("RTU License"), to operate the specific Equipment, processor or
-----------
product line for which the licenses to use the Software are initially granted,
or temporarily on any comparable replacement if any such Equipment, processor or
product line becomes inoperative. Owner shall use such Software only for its
own internal business operation. The RTU License grants Owner no right to, and
Owner will not, sublicense such Software or modify, decompile, or disassemble
Software furnished as object code to generate corresponding source code provided
in each of the Systems. Except as provided below, no license is granted to
Owner to use the Software outside of the United States.

In the event that Owner wishes to use the Software on associated equipment
outside of the United States or to transfer Software to an affiliate or third
party transferee located outside the United States, Vendor shall not
unreasonably withhold its consent to such use or transfer, provided that Vendor
-------- ----
or the transferee, as the case may be, enters into an appropriate license
agreement with an affiliate of Vendor carrying on business in the territory in
which the Software is to be located, on terms substantially similar to the RTU
License terms set forth herein, provided, however, that Owner acknowledges and
agrees that support and maintenance obligations set forth herein are only
applicable for Software resident on Equipment located within the United States.
Support and maintenance Services offered by Vendor's affiliates differs in
various different territories, and will be subject to the local practices
maintained in such territory.

13.2 Owner's Obligations. The Owner agrees that the Software,
-------------------
whether or not modified, and all copies thereof made by Owner, shall be treated
as proprietary to the Vendor, its Subcontractors or its suppliers, as
appropriate and the Owner shall:

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

(a) Utilize the Software solely in conjunction with a System;

provided that the Vendor acknowledges that the Software shall be integrated
- -------- ----
across interfaces with systems, equipment and software provided by other
suppliers and customers;

(b) Ensure that all copies of the Software shall, upon any
reproduction by the Owner authorized by the Vendor and whether or not in the
same form or format as such Software, contain the same proprietary,
confidentiality and copyright notices or legends which appear on the Software
provided pursuant hereto; and

(c) Hold secret and not disclose the Software to any person, except
to (i) such of its employees, contractors, agents or affiliates that are
involved in the operation or management of a System and need to have access
thereto to fulfill their duties in such capacity, or (ii) other Persons who need
to use such Software to permit integration of a System with systems and software
of other suppliers and customers; provided that such persons agree, or are
-------- ----
otherwise obligated, to hold secret and not disclose the Software to the same
extent as if they were subject to this Contract, and provided further that if
any such Person is a competitor of Vendor involved in the manufacture of
communications equipment, software or related services, Vendor must approve such
use on a case-by-case basis on commercially reasonable terms and such use shall
be subject to an appropriate non-disclosure agreement.

(d) When and if the Owner determines that it no longer needs the
Software or if the Owner's license is canceled or terminated pursuant to the
terms of this Contract, return all copies of such Software to the Vendor or
follow reasonable written disposition instructions provided by the Vendor. If
the Vendor authorizes disposition by erasure or destruction, the Owner shall
remove from the medium on which Software resides all electronic evidence of the
Software, both original and derived, in such manner that prevents subsequent
recovery of such original or derived Software.

(e) Owner shall not copy Software embodied in firmware and unless
otherwise specifically provided in this Contract, Owner is not granted any right
to modify Software furnished by Vendor under this Contract.

13.3 Backwards Compatibility. The Vendor represents and warrants
-----------------------
(the "Software Backwards Compatibility Warranty") that each Software Maintenance
-----------------------------------------
Release, Software Upgrade and Software Enhancement will be Backwards Compatible.
[***] Notwithstanding the foregoing, the Software Backwards Compatibility
Warranty does not apply to Products developed AXE in accordance with standards
not yet finalized as of the date hereof.

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

13.4 Transfer and Relocation. (a) In the event the Owner or any
-----------------------
successor to the Owner's title in the Products: (i) elects to transfer a
Product to a third party, and where such Product shall remain in place and used
for substantially the same purpose as used by the Owner and where such third
party resides in the United States and is not a direct competitor of the Vendor
involved in the manufacture of communications equipment, software or related
services; or (ii) elects to transfer Products to an affiliate, the Owner may
transfer its RTU License for the Software furnished under this Contract for use
with such Product, without the payment of any additional Software right-to-use
fees by the transferee provided that Annual Maintenance Fees shall continue to
-------- ----
be calculated on the same basis. For example, if the RTU License for the
Software contains usage or per subscriber limits, or the processor to be used by
transferee requires additional memory or hard disk space additional payments or
purchases may be required. The following conditions shall apply to transfers
and relocations pursuant to this subsection 13.4:

(A) The right to use such Software may be transferred only together
with the Products with which the Owner has a right to use such
Software, and such right to use the Software shall continue to be
limited to use with such Products;

(B) Before any such Software is transferred, the Owner shall notify
the Vendor of such transfer and the transferee shall have agreed
in writing (a copy of which shall be provided to the Vendor) to
keep the Software in confidence and to corresponding conditions
respecting possession and use of Software as those imposed on the
Owner in this Contract; and

(C) The transferee shall have the same right to Software warranty and
Software maintenance for such Software as the transferor,
provided the transferee continues to pay the fees, including
recurring fees, if any, associated with such Software warranty or
maintenance pursuant to this Contract.

(b) Except as otherwise provided in this Contract, the Owner or any
successor to the Owner's title in the Products shall have no right to transfer
Software furnished by the Vendor under this Contract without the consent of the
Vendor, which consent shall not be unreasonably withheld. If the Owner or such
successor elects to transfer a Product purchased under this Contract for which
it does not under this Contract have the right to transfer related Software, the
Vendor agrees that upon written request of the transferee of such Product, or of
the Owner or such successor, the Vendor shall not without reasonable cause fail
to grant to the transferee a license to use such Software with the Products,
whether to be located within the United States or elsewhere, upon payment of a
relicensing fee to the Vendor on commercially reasonable terms acceptable to
Vendor.

13.5 Termination and Survival. The rights and obligations of the
------------------------
Owner under the RTU License shall survive the termination of this Contract,
regardless of the cause of termination provided Owner has met its material
obligations hereunder and has rendered all payments in accordance with this
Contract. In the event that Owner persistently and materially breaches its
confidentiality obligations hereunder with respect to the Software,
notwithstanding the fact that Vendor will have provided Owner with prior written
notice describing the alleged material breaches

and will have given Owner a reasonable time, and in no event less than thirty
(30) days, to cure any such breaches, Vendor may terminate Owner's RTU License.
In the event that Owner fails to pay the Annual Release Maintenance Fees (other
than with respect to any periods for which no payment for Annual Release
Maintenance Fees are due pursuant to this Contract), Vendor may terminate
Owner's right to use the Software to which such fees apply. In no event other
than as set forth in this subsection 13.5 may Vendor terminate Owner's right to
use the Software. Notwithstanding any other provision of this Contract, if there
is a dispute, pending final resolution of such dispute, all of Owner's rights
under this Contract shall continue in full force and effect, and Vendor will not
terminate the RTU License, and so long as Owner continues to pay Vendor
applicable Annual Maintenance Release Fees, Vendor will not terminate, suspend,
interrupt or delay maintenance and support of the Software.

13.6 Access to Source Codes. The Vendor represents and warrants that
----------------------
as of the date hereof, Vendor has not established a Source Code escrow for any
of its existing customers. In the event that Vendor establishes a Source Code
escrow in the future which applies to any of the Software furnished to Owner
hereunder, Vendor shall add Owner as a beneficiary of such Source Code escrow,
and Owner shall be entitled to receive a copy of the escrowed Source Code in the
event of the occurrence of any of the events set out below. In addition to the
foregoing, the Vendor shall immediately deliver and hereby grants the Owner a
right to access the Source Code and to modify the Software (the "RTM License")
-----------
for the maintenance, enhancement and support of those Products purchased from
the Vendor and owned or operated by the Owner under the following circumstances,
provided that any such released Source Code shall be subject to the
- -------- ----
confidentiality provisions set forth in this Contract:

(i) if the Vendor becomes insolvent, makes a general assignment
for the benefit of creditors, files a voluntary petition in bankruptcy or
an involuntary petition in bankruptcy is filed against the Vendor which is
not dismissed within sixty (60) days, or suffers or permits the appointment
of a receiver for its business, or its assets become subject to any
proceeding under a bankruptcy or insolvency law, domestic or foreign, or
has liquidated its business, or the Vendor, or a business unit of the
Vendor that is responsible for maintenance of the Software, ceases doing
business without providing for a successor, and the Owner has reasonable
cause to believe that any such event shall cause the Vendor to be unable to
meet its Warranty service or support requirements hereunder; or

(ii) if the Vendor ceases to maintain or support a previously
supported version of the Software and Owner cannot obtain, with Vendor's
assistance (for example, by providing a third party with Source Code or by
any other appropriate method) the same support services the Vendor is
required to provide under this Contract from another entity (either working
with or independently from Vendor) at a price that is equal to or less than
the prices for such support as provided herein, or there is a persistent
and material failure by Vendor to provide the Warranty service or support
it is required to provide pursuant to the terms of this Contract.

13.7 Ownership of Intellectual Property. The Vendor shall own all
----------------------------------
forms of intellectual property rights (including, but not limited to, patent,
trade secret, copyright and mask rights) pertaining to the Software, and shall
have the right to file for or otherwise secure and protect

such rights. The foregoing notwithstanding, the parties understand and agree
that from time to time the Owner may devise, develop or otherwise create ideas
or other concepts for services or new products which are patentable or otherwise
capable of receiving protection from duplication. In such event, the Owner
shall have the right to apply for a patent in accordance with applicable law,
provided, however, that notwithstanding this subsection, the Vendor does not
- -------- -------
hereby relinquish or release any of its intellectual property rights.

-------------------------------------
testing of the Software by the Vendor and the acceptance thereof by the Owner
shall be performed in accordance with the criteria set forth in Exhibit G.

14.1.4 Software Fixes. In the event that any Software Maintenance
--------------
Release, Software Upgrade, Software Enhancement or Software Combined Release
supplied by the Vendor during the term of this Contract has the effect of
preventing any System or any part thereof from satisfying, or performing in
accordance with the Specifications or the Exhibits or otherwise adversely
affects the functionality or features of any System or any part thereof, then
the Vendor shall promptly retrofit or take such other corrective action as may
be necessary to ensure that any System or any such affected part, as modified to
include each such Software Maintenance Release, Software Upgrade, Software
Enhancement or Software Combined Release, shall satisfy, and perform in
accordance with, the Specifications and the Exhibits and restore all pre-
existing functionality and features as well as provide any new features and
functionality provided by any of the foregoing modifications, in each case
without any charge to the Owner (other than payment of the applicable fees
pursuant to the terms of this Contract). Notwithstanding anything contained

herein in this subsection to the contrary, Owner shall be responsible for the
cost of any additional Equipment required to accommodate additional capacity,
memory or processing requirements necessitated by any new Software feature or
Optional Software Feature which Owner elects to use (provided such use by Owner
is optional without losing the benefit of the Software Maintenance Release or
Software Upgrade) which are contained in any such Software Upgrade, Software
Enhancement or Software Combined Release; provided, however, that Owner shall
-------- -------
not be required to pay for any additional Equipment required to accommodate
additional capacity, memory or processing requirements necessitated by

through the Vendor's design change management system or another Vendor
notification procedure. Each change notification, whether or not it bears a
restrictive legend, will be subject to the confidentiality obligations
provided in subsection 26.18, except that such information may be
reproduced by the Owner for the Owner's use as required within the System.
If the Vendor has engineered, furnished, and installed a Product which is
subject to an Equipment Upgrade, the Vendor will implement such change, at
its sole cost and expense, if it is announced within [*] for the AXE switch
and [*] for all other Products from the date of shipment of that Product,
and subject to the reasonable review and acceptance of the Owner at such
times as the Owner reasonably determines that it needs to review such
Vendor decision, by either (A) modifying the Product at the Owner's site;
(B) modifying the Product which the Owner has returned to the Vendor in
accordance with the Vendor's reasonable instructions pursuant to and in
accordance with the terms of this Contract; or (C) replacing the Product
requiring the change with a replacement Product for which such change has
already been implemented. If the Vendor has not engineered the original
Product application and accordingly office records are not available to the
Vendor, the Vendor will provide the generic change information and
associated parts for the Owner's use in implementing such change.

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

(ii) In any of the instances described in clause (i) above, if
the Vendor and the Owner agree that a Product or part thereof subject to
such change is readily returnable, without incurring any significant time
or expense, the Owner, at its expense, will remove and return such Product
or part to the Vendor's designated facility within the United States and
the Vendor, at its sole expense, will implement such change (or replace it
with a Product or part for which such change has already been implemented)
at its facility and return such changed (or replacement) Product or part at
its sole cost and expense to the Owner's designated location within the
United States. Any such reinstallation of Products which were readily
returnable will be performed by the Owner at its sole expense, provided
such reinstallation can be done by Owner without incurring any significant
time or expense. In all other circumstances, Vendor shall provide such
removal, repair and reinstallation Services at its sole cost and expense.

(iii) If the Owner does not make or permit the Vendor to make an
Equipment Upgrade as stated above within the appropriate [*] or [*] period
from the date of change notification or such other period as the Vendor may
agree, subsequent changes, repairs or replacements affected by the failure
to make such change may, at the Vendor's option, be invoiced to the Owner
whether or not such subsequent change, repair or replacement is covered
under the warranty provided in this Contract for such Product. If
requested by the Owner, Equipment Upgrades announced more than the
appropriate [*] or [*] period from the date of shipment will be implemented
at the Owner's expense.

(iv) If the Vendor issues an Equipment Enhancement after a
Product has been shipped to the Owner, the Vendor will promptly notify the
Owner of such change if it is being offered to any of the Vendor's
customers. Except as otherwise set forth above in subsection 14.2(b), when
an Equipment Enhancement is requested by the Owner, the pricing set for
such Equipment Enhancements will be at the Vendor's standard charges
subject to the applicable discounts set forth in the B Exhibits.

(v) All change notifications for Equipment Upgrades and
Equipment Enhancements provided by the Vendor to the Owner pursuant to the

---------------
Equipment Enhancement, directly or indirectly, supplied by the Vendor during the
appropriate [*] or [*] period following the Effective Date or during [*] period
following the date of shipment of such Equipment Upgrade or Equipment
Enhancement, has the effect of preventing any System or any part thereof from
satisfying, or performing in accordance with, the Specifications or otherwise
adversely affects the functionality, interoperability or features of any System,
or any part thereof then the Vendor shall without any charge to the Owner
promptly retrofit or take such other corrective action as may be necessary to

SECTION 15. INTELLECTUAL PROPERTY

15.1 Intellectual Property. Neither Owner nor Vendor shall publish
---------------------
or use any advertising, sales promotion, press releases or publicity matters
relating to this Contract without the prior written approval of the other, in
accordance with subsection 26.13.

15.2 Infringement. (a) The Vendor agrees that it shall defend,
------------
indemnify and hold harmless, at its own expense, all suits and claims against
the Owner for infringement or violation of any patent, trademark, copyright,
trade secret or other intellectual property rights of any third party
enforceable in the United States or in any other territory where Vendor has
approved the deployment or use of Products under this Contract (collectively,
"Intellectual Property Rights"), covering, or alleged to cover, the Products or
- -----------------------------
any component thereof. The Vendor agrees that it shall pay all sums, including
without limitation, reasonable attorneys' fees and other costs incurred at
Vendor's written request or authorization, which, in defense of, by final
judgment or decree, or in settlement of any suit or claim to which the Vendor
agrees, may be assessed against, or incurred by, the Owner on account of such
infringement or violation, provided that the Owner shall cooperate in all
-------- ----
reasonable respects with the Vendor and its attorneys in the investigation,
trial and defense of such lawsuit or action and any appeal arising therefrom;
provided, however, that the Owner may, at its own cost, participate in the
investigation, trial and defense of such lawsuit or action and any appeal
arising therefrom. The parties shall cooperate with each other in any
notifications to insurers. If a claim for Losses (a "Claim") is to be made by a
-----
party entitled to indemnification hereunder against the Vendor, the party
claiming such indemnification shall give written notice (a "Claim Notice") to
------------
the Vendor as soon as practicable after the party entitled to indemnification
becomes aware of any fact, condition or event which may give rise to Losses for
which indemnification may be sought under this Agreement, provided, however, no
delay on the part of the Owner in notifying the Vendor shall relieve the Vendor
from any obligation hereunder unless (and then solely to the extent) the Vendor
is thereby materially prejudiced. If any lawsuit or enforcement action is filed
against any party entitled to the benefit of indemnity hereunder, written notice
thereof shall be given to the Vendor as promptly as practicable (and in any
event within twenty (20) calendar days after the service of the citation or
summons). The Vendor shall be entitled, if it so elects to: (i) defend such
lawsuit or action; (ii) employ and engage attorneys of its own choice to handle
and defend the same, at the Vendor's cost, risk and expense; and (iii)
compromise or settle such Claim, which compromise or settlement shall be made
only with the written consent of the Owner (which may not be unreasonably
withheld),

unless such compromise or settlement includes an unconditional release of any
claims against the Owner in which event such written consent of the Owner shall
not be required. If the Vendor fails to assume the defense of such Claim within
twenty (20) calendar days after receipt of the Claim Notice, the Owner against
which such Claim has been asserted will (upon delivering notice to such effect
to the Vendor) have the right to undertake, at the Vendor's cost and expense,
the defense, compromise or settlement of such Claim on behalf of and for the
account and risk of the Vendor. In the event the Owner assumes the defense of
the Claim, the Owner will keep the Vendor reasonably informed of the progress of
any such defense, compromise or settlement. The Vendor shall be liable for any
settlement of any action effected pursuant to and in accordance with this
Agreement and for any final judgment (subject to any right of appeal), and the
Vendor agrees to indemnify and hold harmless the Owner from and against any
Losses by reason of such settlement or judgment.

(b) The Vendor's obligation under this subsection shall not extend to
alleged infringements or violations that arise because the Products provided by
the Vendor are used in combination with other products furnished by third
parties and where any such combination was not installed, recommended or
approved by the Vendor.

15.3 Vendor's Obligation to Cure. If in any such suit so defended,
---------------------------
all or any part of the Products or any component thereof is held to constitute
an infringement or violation of Intellectual Property Rights of others and its
use is enjoined, or if in respect of any claim of infringement or violation the
Vendor deems it advisable to do so, the Vendor shall at its sole cost, expense
and option take one or more of the following actions: (i) procure the right to
continue the use of the same without interruption for the Owner; (ii) replace
the same with non-infringing Products that meets the Specifications in
accordance with the terms of this Contract; or (iii) modify said Products, any
System or any component thereof so as to be non-infringing, provided that the
-------- ----
Products, any System or any component thereof as modified meets all of the
Specifications. In the event that the Vendor is not able to cure the
infringement pursuant to clause (i), (ii) or (iii) in the immediately preceding
sentence, in addition to the other rights and remedies provided in this Section
15, the Vendor shall refund to the Owner the full purchase price paid by the
Owner for such infringing Product or feature, and the Owner shall be under no
obligation to return to the Vendor such infringing Product or feature regardless
of whether, or by what means, the Owner, on its own or otherwise, subsequently
cures such infringement, unless Owner is directed to do so by court order.

15.4 Vendor's Obligations. The Vendor's obligations under this
--------------------
Section 15 shall not apply to any infringement or violation of Intellectual
Property Rights caused by unauthorized modification of the Products, any System
or any component thereof by the Owner, or arises from adherence to instructions
to apply Owner's trademark, trade name or other company identification to a
Product, or any infringement caused solely by the Owner's use and maintenance of
the Products other than in accordance with the Specifications, except as
authorized or permitted by the Vendor. The Owner shall indemnify the Vendor
against all liabilities and costs, including reasonable attorneys' fees, for
defense and settlement of any and all claims against the Vendor for
infringements or violations based upon this subsection.

15.5 Liability of Vendor. The Liability of Vendor with respect to
-------------------
any and all claims, actions, proceedings or suits by third parties alleging
infringement of patents, trademarks, or copyrights or violation of trade secrets
or proprietary rights because of, or in connection with, any items furnished
pursuant to this Contract shall be limited to the specific undertakings
contained in this Section 15.

SECTION 16. DELAY

16.1 Liquidated Damages. The parties agree that damages for delay
------------------
are difficult to calculate accurately and not reasonably determinable at the
time of execution of this Contract, and, therefore, agree that liquidated
damages (the "Liquidated Damages") shall be paid for non-performance or late
------------------
performance of the Vendor's obligations to achieve a Guaranteed Substantial
Completion Date for reasons not otherwise excused by Force Majeure or Owner's
failure to satisfy its obligations set out in this Contact. The parties agree
that Liquidated Damages are intended to compensate Owner for the delayed or late
performance by the Vendor and are not a penalty.

16.2 Delay and Default. In the event the Vendor fails to achieve
-----------------
(other than as permitted by this Contract) the Substantial Completion of a
System on or before the Guaranteed Substantial Completion Date for such System
or during a ten day cure period following such date, the Vendor shall pay,
weekly in arrears, for the next [*] commencing on the eleventh day after the
Guaranteed Substantial Completion Date, Liquidated Damages to the Owner in an
amount equal to [*] (pro-rated on a daily basis for periods of time less than
one week) of the total amount of all Purchase Orders relating to the System with
respect to which the Vendor has so failed, based on the number of days elapsed
after a ten day cure period following the Guaranteed Substantial Completion
Date and before the achievement of Substantial Completion; provided that in the
-------- ----
event that Substantial Completion is not achieved prior to the expiration of
such [*] period, thereafter Vendor shall pay, weekly in arrears, additional
Liquidated Damages to the Owner in an amount equal to [*] (pro-rated on a daily
basis for periods of time less than one week) of the total amount of all
Purchase Orders relating to the System with respect to which the Vendor has so
failed, based on the number of days elapsed after the [*] plus ten (10) day
cure period following the Guaranteed Substantial Completion Date and before the
achievement of Substantial Completion; provided that in no event shall the
-------- ----
amount of Liquidated Damages so paid in respect of a System exceed [*] of the
total amount of all Purchase Orders relating to the System with respect to which
the Vendor has so failed.

16.3 System Capacity Guarantee. Vendor guarantees (the "Capacity
------------------------- --------

SECTION 18. WARRANTIES

18.1 Equipment and Services Warranty. Vendor warrants that, with
-------------------------------
respect to each System, for a period of two (2) years from the date of
Substantial Completion, provided, however that if prior to Final Acceptance a
Major Outage occurs, the two (2) year period shall be extended by the number
of days elapsed between Substantial Completion and the date the Owner signs the
Certificate of Final Acceptance (as so determined, the "Warranty Period"), all
---------------
Equipment and Services furnished under this Contract with respect to such System
will be free of Defects and Deficiencies and shall conform to the applicable
portions of the Specifications (the "Equipment and Services Warranty"),
-------------------------------
provided, however, that with respect to those Services for which a warranty is
set forth in an Exhibit, the warranty contained in the Exhibit shall supersede
the general Services warranty contained in this Section 18.1. With respect to
third-party manufactured Products which are not a part of a Core System, Vendor
shall furnish such Products only on a pass-through warranty basis; provided,
however, that Vendor shall identify such Products to Owner before acceptance of
any Purchase Order which includes any such Products. The terms of the warranty
applicable to such Products shall be provided in an addendum to the Purchase
Order. Except as noted in the B

Exhibits, all Products referenced in the B Exhibits qualify as Vendor-warranted
Products. The Vendor's obligations with respect to the Equipment and Services
Warranty shall be to attempt first to repair or replace at no additional cost,
any defective Equipment or correct any deficient Services. If, after using its
best efforts to repair or replace such Product and after consultation with and
with the consent of Owner, which consent shall not be unreasonably withheld,
Vendor determines that it is unable to repair, replace or otherwise correct such
defect, Vendor shall provide a credit or refund based on the original purchase
price, and installation charges if installed by Vendor. If, as a result of the
Defect and Deficiency, the Product fails to operate in accordance with the
Specifications which causes the System to fail to materially operate in
accordance with its Specifications, a refund shall be paid to the Owner on
account of the purchase price for the total System, less a pro-rata discount
calculated with regard to the period of time during the Warranty Period that
Owner operated the System in In Revenue Service. For purposes of calculating
such pro rata discount, the period of time the Owner would have been able to
operate the System within In Revenue Service shall be: (i) ten (10) years from
Substantial Completion for the AXE switch; and (ii) seven (7) years from
Substantial Completion for all other Products. In the event that Vendor pays a
refund hereunder, Owner shall return such Products to Vendor at Vendor's sole
cost and expense. The Warranty Period for all Equipment or Services repaired,
replaced or corrected under the Equipment and Services Warranty shall be the
longer of: (i) one (1) year from the date of delivery of the repaired or
replacement Equipment or from the completion of the corrected Services, as
applicable; or (ii) or the unexpired term of the Warranty Period. The Warranty
Period for Equipment purchased as spares shall be two (2) years from
installation of such Equipment.

For those Products not readily returnable by Owner, or where Owner cannot
remove and reinstall the Products without incurring significant time and
expense, and where Vendor elects to repair or replace the Product, Vendor shall
repair or replace the Product at Owner's Site. In the event Vendor does the
repair work at Owner's site, Vendor shall be responsible for replacement of
cable and wire Products, and for reasonable Site restoration. If Vendor has
elected to repair or replace a defective Product, and the Product is readily
returnable by Owner without incurring significant work or expense, Owner is
responsible for removing and reinstalling the Products. Products returned for
repair or replacement will be accepted by Vendor only in accordance with its
instructions and procedures for such returns. The transportation expense
associated with returning such Product to Vendor shall be borne by Owner.
Vendor shall pay the cost of transportation of the repaired or replacing Product
to the return destination designated by Owner. Defective or nonconforming
Products or parts which are replaced hereunder shall become Vendor's property.
Vendor may use either the same or functionally equivalent new, remanufactured,
reconditioned or refurbished Products or parts in the furnishing of repairs or
replacements under this Contract, provided that such Products satisfy the
-------- ----
Specifications.

18.2 Expansions Warranty. Vendor warrants that, with respect to
-------------------
Products and Services constituting Expansions (including Expansions to a System,
or Expansions or growth not part of a System, and all other purchased Products)
furnished under this Contract will be free of Defects and Deficiencies and shall
conform the applicable portions of the Specifications (the "Expansions
----------
Warranty"). The warranty period with respect to such Products and Services
shall be two (2) years from the date of installation completion or completion
of Services, as the case may be (the "Expansions Warranty Period"). With
--------------------------
respect to third-party manufactured Products which are not a part of a Core
System, Vendor shall furnish such Products only on a pass-through warranty

basis; provided, however, that Vendor shall identify such Products to Owner
before acceptance of any Purchase Order which includes any such Products. The
terms of the warranty applicable to such Products shall be provided in an
addendum to the Purchase Order. Except as noted in the B Exhibits, all Products
referenced in the B Exhibits qualify as Vendor-warranted Products. The Vendor's
obligations with respect to the Expansions Warranty shall be to attempt first to
repair or replace at no additional cost, any defective Equipment or correct any
deficient Services. If, after using its best efforts to repair or replace such
Product and after consultation with and with the consent of Owner, which consent
shall not be unreasonably withheld, Vendor determines that it is unable to
repair, replace or otherwise correct such defect, Vendor shall provide a credit
or refund based on the original purchase price, and installation charges if
installed by Vendor. The warranty period for all Equipment or Services
repaired, replaced or corrected under the Expansions Warranty shall be the
longer of: (i) one (1) year from the date of delivery of the repaired or
replacement Equipment or from the completion of the corrected Services, as
applicable; or (ii) the unexpired term of the Expansions Warranty Period. The
Warranty Period for Equipment purchased as spares shall be two (2) years from
installation of such Equipment.

18.3 Software Warranty. Vendor warrants that, with respect to each
-----------------
System for the Warranty Period, all Software will be free of Defects and
Deficiencies and shall conform to the applicable portions of the Specifications
(the "Software Warranty"). The Vendor's obligations with respect to the
-----------------
Software Warranty shall be to attempt first to repair or replace at no
additional cost, any defective Software. If, after using its best efforts to
repair or replace such Software and after consultation with and with the consent
of Owner, which consent shall not be unreasonably withheld, Vendor determines
that it is unable to repair, replace or otherwise correct such defect, Vendor
shall provide a credit or refund based on the original purchase price, and
installation charges if installed by Vendor. If, as a result of the Defect and
Deficiency, the Software fails to operate in accordance with the Specifications
which causes the System to fail to materially operate in accordance with its
Specifications, a refund shall be paid to Owner on account of the purchase price
for the total System, less a pro rata discount calculated with regard to the
period of time during the Warranty Period that Owner operated the System in In
Revenue Service. For purposes of calculating such pro rata discount, the period
of time the Owner would have been able to operate the System In Revenue

Service shall be: (i) ten (10) years from Substantial Completion for the AXE
switch; and (ii) seven (7) years from Substantial Completion for all other
Products. In the event that Vendor pays a refund hereunder, Owner shall return
such Products to Vendor. The warranty period for all Software so corrected or
replaced under the Software Warranty shall be the longer of: (i) one (1) year
from the date of delivery of the repaired or replacement Software; or (ii) or
the unexpired term of the Warranty Period. Vendor shall be solely responsible
for all costs and expenses incurred by Owner or Vendor in connection with the
de-installation, removal and transportation of defective Software under the
Software Warranty and for the transportation and installation of repaired,
corrected or replacement Software, including without limitation any additional
or upgraded Equipment or processing capability necessary to run or operate such
repaired, corrected or replacement Software. The Warranty Period with respect to

which Vendor would otherwise have been required to deliver to Owner
pursuant to the terms of this Contract but for the breach, under reasonably
appropriate non-disclosure agreements; or

(ii) direct that the Vendor assign its Subcontractor agreements
to the Owner without any change of price or conditions therein or penalty
or payment therefor.

(c) In the event of any termination of this Contract by Owner in
connection with a Vendor Event of Default, Owner shall have no liability for any
failure to satisfy the Minimum Purchase Commitment prior to such termination.

24.4 Discontinuance of Work. Upon such notification of termination,
----------------------
the Vendor shall immediately discontinue all of the Work (unless such notice of
termination directs otherwise), and, as more fully set forth in subsection
24.3(b), deliver to the Owner copies of all data, drawings, specifications,
reports, estimates, summaries, and such other information, and materials as may
have been accumulated by the Vendor in performing the Work, whether completed or
in process, which Vendor would otherwise have been required to deliver to Owner
pursuant to this Contract but for the breach. Furthermore, the Vendor shall
assign, assemble and deliver to the Owner all purchase orders and Subcontractor
agreements requested by the Owner.

24.5 Payments. If the Owner terminates this Contract pursuant to
--------
subsection 24.2, the Vendor shall not be entitled to receive further payment
other than payments due and payable under this Contract and not subject to
dispute prior to such termination (provided that any such disputed amounts shall
-------- ----
be paid by the Owner when and if such dispute is in fact resolved).
Notwithstanding anything herein to the contrary, the Owner may withhold
payments, if any, to the Vendor for the purposes of offset of amounts owed to
the Owner pursuant to the terms of this Contract until such time as the exact
amount of damages due the Owner from the Vendor is fully determined by a court
of competent jurisdiction.

24.6 Continuing Obligations. Termination of this Contract for any
----------------------
reason (i) shall not relieve either party of its obligations with respect to the
confidentiality of the Proprietary Information as set forth in subsection 26.18;
(ii) shall not relieve either party of any obligation which applies to it and
which expressly or by implication survives termination; and (iii) except as
otherwise provided in any provision of this Contract expressly limiting the
liability of either party, shall not relieve either party of any obligations or
liabilities for loss or damage to the other party arising out of or caused by
acts or omissions of such party prior to the effectiveness of such

termination or arising out of its obligations as to portions of the Work already
performed or of obligations assumed by the Vendor prior to the date of such
termination.

24.7 Vendor's Right to Terminate. The Vendor shall have the option
---------------------------
to terminate this Contract without any penalty or payment obligations, other
than undisputed payment obligations outstanding as of the date of any such
termination pursuant to the terms of this Contract if:

(a) the Owner (i) files a voluntary petition in bankruptcy or has an
involuntary petition in bankruptcy filed against it that is not dismissed within
sixty (60) days of such involuntary filing: (ii) admits the material
allegations of any petition in bankruptcy filed against it; (iii) is adjudged
bankrupt; (iv) makes a general assignment for the benefit of its creditors, or
if a receiver is appointed for all or a substantial portion of its assets and is
not discharged within sixty (60) days after his appointment; or (v) commences
any proceeding for relief from its creditors in any court under any state
insolvency statutes, and any such filing, proceeding, adjudication or assignment
as described herein above shall otherwise materially impair the Owner's ability
to perform its obligations under this Contract; or

(b) the Owner fails to make payments of undisputed amounts due to the
Vendor pursuant to the terms of this Contract which are more than sixty (60)
days overdue, provided that such failure has continued for at least thirty (30)
-------- ----
days after the Vendor has notified the Owner of its right and intent to so
terminate on account of such overdue amount; and provided, further, that such
failure to make undisputed payments to Vendor shall not arise out of or relate
to a termination of or credit restrictions under the Vendor Financing, or

(c) the Owner materially breaches any provision of this Contract
other than a breach to which subsection 24.7(b) is applicable, and after the
Vendor having provided thirty (30) days' prior written notice, the Owner shall
have failed to: (i) commence to cure the default within five (5) Business Days
of delivery of such notice; and (ii) diligently pursue such cure and remedy the
breach entirely.

24.8 Special Termination Events. (a) Anytime prior to eighteen (18)
--------------------------
months before termination or expiration of the Availability Period, Vendor, at
its option, may unilaterally extend the Availability Period. Availability
Period is defined in the documentation of the Vendor Financing.

(b) [***]

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

[***]

(c) If at any time after the Effective Date any material change shall
have occurred in any Applicable Law or in the interpretation thereof by any
Governmental Entity, or there shall be rendered any decision in any judicial or
administrative case or proceeding, in either case which, in the reasonable
opinion of the Owner would make the Owner's use of any part of any System
illegal or would subject the Owner or any of its Affiliates to any material
penalty, other material liability or onerous condition or to any burdensome
regulation by any Governmental Entity or otherwise render the use of such System
economically nonviable, then, with respect to such System, or affected part
thereof, or with respect to all Systems if so affected, the Owner may terminate
this Contract without charge or penalty of any kind; provided that (i) the Owner
-------- ----
gives the Vendor prior written notice of any such change or decision and (ii)
that the Owner uses its reasonable efforts for a reasonable time to reverse or
ameliorate such change or decision to the extent possible or practical prior to
declaring such termination. In the event of a termination pursuant to this
subsection, payment obligations incurred by the Owner for Work actually done or
Products or Services actually delivered by the Vendor prior to such termination
pursuant to this Contract shall be payable by the Owner to the Vendor on the
same terms and subject to the limitations set forth in subsection 24.8(a) above.

SECTION 25. SUSPENSION

25.1 Owner's Right to Suspend Work. The Owner may at any time issue
-----------------------------
a Change Order to the Vendor to suspend all or any part of the Work for such
period of time as the Owner may reasonably determine to be appropriate. Any
such Change Order shall be handled in accordance with the provisions of Section
11 hereof.

SECTION 26. MISCELLANEOUS

26.1 Amendments. The terms and conditions of this Contract may only
----------
be amended by mutually agreed contract amendments. Each amendment shall be in
writing and shall identify the provisions to be changed and the changes to be
made. Contract amendments shall be signed by duly authorized representatives of
each of the Vendor and the Owner.

26.2 Owner Liabilities. Vendor understands and agrees that no third
-----------------
party shall guarantee or otherwise be in any way liable with respect to any
obligations or liabilities of the Owner or any of its affiliates pursuant to
this Contract.

26.3 Offset. The Vendor hereby waives any right of offset of amounts
------
owed by the Owner to the Vendor pursuant to the terms of this Contract.

26.4 Assignment. The Owner may assign this Contract, or any part
----------
hereof, to any Affiliate of Owner without the Vendor's approval or consent.
Subject to the foregoing and except as otherwise permitted herein, neither this
Contract nor any portion hereof may be assigned by either party without the
express prior written consent of the other party. The Owner may, without

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

the consent of the Vendor, collaterally assign its rights hereunder (including
but not limited to all licenses with respect to the Software) to any or all
parties providing financing for any part of a System for the benefit of the
Vendor and one or more other entities providing financing for any part of a
System or similar arrangement for the benefit of the Vendor and one or more
other entities providing for the financing for any part of a System, in either
case, which arrangement, as the case may be, is reasonably acceptable to the
Vendor in accordance with the terms of the financing documents. If requested by
the Owner, the Vendor shall within seven (7) calendar days of such request
provide a written consent to any such assignment; provided that such consent
-------- ----
shall permit reassignment if the financing parties exercise their remedies under
the documents for such financing subject to reasonable standards as to: (i) the
creditworthiness of the assignee; and (ii) the fact that the assignee is not at
such time a direct competitor of the Vendor involved in the manufacture of
communications equipment, software or related services. The foregoing rights
and obligations are in addition to those set forth elsewhere in this Contract.
Any attempted assignment in violation of the terms of this Contract shall be
null and void. Subject to the foregoing, this Contract shall bind and inure to
the benefit of the parties to this Contract, their successors and permitted
assigns. Notwithstanding the foregoing, Vendor shall have the right to assign
this Contract to its affiliate, Ericsson Inc.; provided however, such assignment
shall not relieve Vendor of its obligations hereunder or cause Owner to incur
any additional costs or expenses.

26.5 Notices. Except as otherwise expressly stated herein, all
-------
notices, requests, demands and other communications which are required or may be
given under this Contract shall be in writing and shall be deemed to have been

hereby waives, to the extent not prohibited by applicable law, and agrees not to
assert, by way of motion, as a defense or otherwise, in any such action, any
claim that it is not subject personally to the jurisdiction of the above-named

forum or otherwise. Each party hereby consents to service of process in any
such proceeding in any manner permitted by California law, and agrees that

all Applicable Laws in the performance of this Contract, including, without
limitation, the laws and regulations of the United States Department of
Commerce, State Department and the Federal Communications Commission and any
other applicable agency or department.

26.10 Headings. The headings given to the Sections and subsections
--------
herein are inserted only for convenience and are in no way to be construed as
part of this Contract or as a limitation of the scope of the particular Section
or subsection to which the title refers.

26.11 Severability. Whenever possible, each provision of this
------------
Contract shall be interpreted in such a manner as to be effective and valid
under such applicable law, but, if any provision of this Contract shall be held
to be prohibited or invalid in any jurisdiction, the remaining provisions of
this Contract shall remain in full force and effect and such prohibited or
invalid provision shall remain in effect in any jurisdiction in which it is not
prohibited or invalid.

26.12 Waiver. Unless otherwise specifically provided by the terms of
------
this Contract, no delay or failure to exercise a right resulting from any breach
of this Contract shall impair such right or shall be construed to be a waiver
thereof, but such right may be exercised from time to time as may be deemed
expedient. If any representation, warranty or covenant contained in this
Contract is breached by either party and thereafter waived by the other party,
such waiver shall be limited to the particular breach so waived and not be
deemed to waive any other breach under this Contract.

26.13 Public Statements and Advertising. (a) Neither party shall
---------------------------------
issue any public statement (or any private statement unless required in the
performance of the Work) relating to or in any way disclosing any aspect of the
Work or any System including the scope, the specific terms of this Contract,
extent or value of the Work or any System. Express written consent of the other
party is required prior to the invitation of or permission to any reporter or
journalist to enter upon the System or any part thereof. The Vendor agrees not
to use for publicity purposes any photographs, drawings and/or materials
describing any System without obtaining the prior written consent of the Owner,
which consent shall not be unreasonably withheld. The Owner agrees not to use
for publicity purposes any photographs, drawings and/or materials describing the
Vendor's products and services without obtaining the prior written consent of
the Vendor, which consent shall not be unreasonably withheld. This subsection
shall not prohibit the provision of necessary information to prospective
Subcontractors and the Vendor's or the Owner's personnel, agents or consultants
or other disclosures which are required by Applicable Law, including without
limitation federal and state securities laws and regulations. All other such
public disclosures by a party require the written consent of the other party.

(b) Each party shall submit to the other proposed copies of all
advertising (other than public statements or press releases) wherein the name,
trademark or service mark of the other party or its affiliates is mentioned; and
neither party shall publish or use such advertising without the other party's
prior written approval. Such approval shall be granted as promptly as possible
and shall not be unreasonably withheld. The parties acknowledge that the
obtaining of prior written approval for each such use pursuant to this
subsection may be an administrative burden. At the request of either party, the
Owner and the Vendor shall establish mutually acceptable guidelines for

the uses specified therein. Such guidelines shall be subject to change from time
to time at the reasonable request of either party.

26.14 Records and Communications. Procedures for keeping and
--------------------------
distributing orderly and complete records of the Work and its progress are
stated in the Exhibits. The procedures so established shall be followed
throughout the course of the Work unless the Owner and the Vendor mutually agree
in advance in writing to revise the procedures. Procedures for communications
among the Owner and the Vendor are stated in the Exhibits. The procedures so
established shall be followed throughout the course of the Work unless the Owner
and the Vendor mutually agree in advance and in writing to revise such
procedure.

26.15 Ownership of Specifications. The Specifications shall
---------------------------
constitute the Proprietary Information of each party to the extent of each
party's contribution to the Specifications. Neither party shall use those parts
of the Specifications contributed by the other party or any part of the
Proprietary Information of the other party for any purpose other than fulfilling
or exercising their respective rights or obligations under this Agreement.

26.16 Financing Requirements. The Vendor acknowledges that the
----------------------
attainment of financing for construction of the System may be subject to
conditions that are customary and appropriate for the providers of such
financing. Therefore, the Vendor agrees to promptly consider any reasonable
amendment to or modification or assignment of this Contract required by such
providers (including, without limitation, any pertinent industrial development
authority or other similar governmental agency issuing bonds for financing of
the System) which do not materially modify the scope of the Vendor's Work in
order to obtain such financing. In the event that any such amendment or
modification materially increases the Vendor's risk or costs hereunder, the
Owner and the Vendor shall negotiate in good faith to adjust pricing matters,
and to equitably adjust such other provisions of this Contract, if any, which
may be affected thereby, to the extent necessary to reflect such increased risk
or costs. In no event shall the Vendor be required to accept any modification
or amendment pursuant to this subsection provide it has a commercially
reasonable basis for such refusal.

26.17 Owner Review, Comment and Approval. To the extent that various
----------------------------------
provisions of this Contract provide for the Owner's review, comment, inspection,
evaluation, recommendation or approval, the Owner may at its option do so in
conjunction and/or consultation with the Vendor. To the extent that this
Contract requires the Owner to submit, furnish, provide or deliver to the Vendor
any report, notice, Change Order, request or other items, the Owner may at its
option and upon written notice to the Vendor designate a representative to
submit, furnish, provide or deliver such items as the Owner's agent therefor.
To the extent that various provisions of this Contract provide that the Owner
may order, direct or make requests with respect to performance of the Work or is
provided access to the System sites or any other site, the Owner may at its
option and upon written notice to the Vendor authorize a representative to act
as the Owner's agent therefor. Upon receipt of such notice, the Vendor shall be
entitled to rely upon such authorization until a superseding written notice from
the Owner is received by the Vendor.

26.18 Confidentiality. (a) All information which is identified as
---------------
proprietary or confidential by the disclosing party, including without
limitation all oral and written information

(including but not limited to determinations or reports by arbitrators pursuant
to the terms of this Contract), disclosed to the other party is deemed to be
confidential, restricted and proprietary to the disclosing party (hereinafter
referred to as "Proprietary Information"). Each party agrees to use
----------- -----------
the Proprietary Information receive from the other party only for the
purpose of this Contract. Except as specified in this Contract, no other rights,
and particularly licenses, to trademarks, inventions, copyrights, patents, or
any other intellectual property rights are implied or granted under this
Contract or by the conveying of Proprietary Information between the parties.
Proprietary Information supplied is not to be reproduced in any form except as
required to accomplish the intent of, and in accordance with the terms of, this
Contract. The receiving party shall provide the same care to avoid disclosure or
unauthorized use of Proprietary Information as it provides to protect its own
similar proprietary information but in no event shall the receiving party fail
to use reasonable care under the circumstances to avoid disclosure or
unauthorized use of Proprietary Information. All Proprietary Information shall
be retained by the receiving party in a secure place with access limited to only
such of the receiving party's employees, subcontractors or agents who need to
know such information for purposes of this Contract and to such third parties as
the disclosing party has consented to by prior written approval. All Proprietary
Information, unless otherwise specified in writing: (i) remains the property of
the disclosing party; (ii) shall be used by the receiving party only for the
purpose for which it was intended; and (iii) such Proprietary Information,
including all copies of such information, shall be returned to the disclosing
party or destroyed after the receiving party's need for it has expired or upon
request of the disclosing party, and, in any event, upon termination of this
Contract. At the request of the disclosing party, the receiving party shall
furnish a certificate of an officer of the receiving party certifying that
Proprietary Information not returned to disclosing party has been destroyed. For
the purposes hereof, Proprietary Information does not include information which:

(i) is published or is otherwise in the public domain through no
fault of the receiving party at the time of any claimed disclosure or
unauthorized use by the receiving party;

(ii) prior to disclosure pursuant to this Contract is properly
within the legitimate possession of the receiving party as evidenced by
reasonable documentation to the extent applicable;

(iii) subsequent to disclosure pursuant to this Contract is
lawfully received from a third party having rights in the information
without restriction of the third party's right to disseminate the
information and without notice of any restriction against its further
disclosure;

(iv) is independently developed by the receiving party or is
otherwise received through parties who have not had, either directly or
indirectly, access to or knowledge of such Proprietary Information;

(v) is transmitted to the receiving party after the disclosing
party has received written notice from the receiving party after
termination or expiration of this Contract that it does not desire to
receive further Proprietary Information;

(vi) is obligated to be produced under order of a court of
competent jurisdiction or other similar requirement of a Governmental
Entity, so long as the party required to disclose the information provides
the other party with prior notice of such order or requirement and its
cooperation to the extent reasonable in preserving its confidentiality; or

(vii) the disclosing party agrees in writing is free of such
restrictions.

(b) Because damages may be difficult to ascertain, the parties agree,
without limiting any other rights and remedies specified herein, an injunction
may be sought against the party who has breached or threatened to breach this
subsection. Each party represents and warrants that it has the right to
disclose all Proprietary Information which it has disclosed to the other party
pursuant to this Contract, and each party agrees to indemnify and hold harmless
the other from all claims by a third party related to the wrongful disclosure of
such third party's proprietary information.

26.19 Entirety of Contract; No Oral Change. This Contract and the
------------------------------------
Exhibits and Schedules referenced herein constitute the entire contract between
the parties with respect to the subject matter hereof, and supersede all
proposals, oral or written, all previous negotiations, agreements [including
without limitation the Memorandum of Agreement dated September 20, 1999 by and
among Vendor, Cricket (as defined in that agreement) and Leap Wireless
International, Inc.] and all other communications between the parties with
respect to the subject matter hereof. No modifications, alterations or waivers
of any provisions herein contained shall be binding on the parties hereto unless
evidenced in writing signed by duly authorized representatives of both parties
as set forth in this Contract.

26.20 Relationship of the Parties. Nothing in this Contract shall be
---------------------------
deemed to constitute either party a partner, agent or legal representative of
the other party, or to create any fiduciary relationship between the parties.
The Vendor is and shall remain an independent contractor in the performance of
this Contract, maintaining complete control of its personnel, workers,
Subcontractors and operations required for performance of the Work. This
Contract shall not be construed to create any relationship, contractual or
otherwise, between the Owner and any Subcontractor, except to establish Owner as
a third party beneficiary of the Vendor's contacts with Subcontractors as
provided herein.

26.21 Discretion. Notwithstanding anything contained herein to the
----------
contrary, to the extent that various provisions of this Contract call for an
exercise of discretion in making decisions or granting approvals or consents,
the parties shall be required to exercise such discretion, decision or approvals
and in good faith.

26.22 Non-Recourse. No past, present or future limited or general
------------
partner in or of the Owner, no parent or other affiliate of any company
comprising the Owner, and no officer, employee, servant, executive, director,
agent or authorized representative of any of them (each, an "Operative") shall
---------
be liable by virtue of the direct or indirect ownership interest of such
Operative in the Owner for payments due under this Contract or for the
performance of any obligation, or breach of any representation or warranty made
by the Owner hereunder. The sole recourse of the Vendor

for satisfaction of the obligations of the Owner under this Contract shall be
against the Owner and the Owner's assets and not against any Operative or any
assets or property of any such Operative. In the event that a default occurs in
connection with such obligations, no action shall be brought against any such
Operative by virtue of its direct or indirect ownership interest in the Owner.

26.23 Improvements, Inventions and Innovations. All rights in any
----------------------------------------
improvements, inventions, and innovations made solely by the Owner shall vest in
the Owner, and the Owner and its affiliates shall have the right to exploit such
improvements, inventions, and innovations. All rights in any improvements,
inventions and innovations made solely by the Vendor shall vest in the Vendor,
and the Vendor and its affiliates shall have the right to exploit such
improvements, inventions and innovations. All rights in any improvements,
inventions and innovations made by the substantial contribution of both parties
("Joint Information") shall vest jointly in both parties. Joint Information
-----------------
does not include any underlying information owned by one of the parties prior to
commencement of such joint activities or developed beyond the scope of such
joint activities, including Products and Product information, technical
information or inventions developed prior to the commencement of any joint
activities, developed outside of the scope of such joint activities or developed
solely by either party. The rights of joint ownership to such Joint Information
shall be rights of full non-exclusive worldwide ownership, including rights to
license and transfer. Each party may exploit its rights to the Joint
Information independent of the other and may retain all economic benefits
thereof, neither party shall have any obligation to account to the other for
profits derived from the Joint Information and each party shall have full rights
to enforce the Joint Information intellectual property rights against non-
authorized users.

26.24 Attachments and Incorporations. All Schedules and Exhibits
------------------------------
attached hereto, are hereby incorporated by reference herein and made a part of
this Contract with the same force and effect as though set forth in their
entirety herein.

26.25 Conflicts. In the event of any conflict or inconsistency among
---------
the provisions of this Contract and the documents attached hereto and
incorporated herein, such conflict or inconsistency shall be resolved by giving
precedence to this Contract and thereafter to the Exhibits, Schedules and
Specifications.

26.26 References to Certain Sources. Reference to standard
-----------------------------
specifications, manuals or codes of any technical society, organization or
association or to the laws or regulations of any Governmental Entity, whether
such reference is specific or by implication, by this Contract, means the latest
standard specification, manual, code, laws or regulations in effect at the time
of such reference, except as may be otherwise specifically agreed to by the
Owner. However, no provision of any reference, standard, specification, manual
or code (whether or not specifically incorporated by reference in this Contract)
shall be effective to change the duties and responsibilities of the Owner or the
Vendor from those set forth in this Contract; provided that nothing contained in
-------- ----
this Contract shall require the Owner or the Vendor to violate then existing and
enforceable Applicable Laws.

26.27 Counterparts. This Contract may be executed by one or more of
------------
the parties to this Contract on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument.

26.28 Cooperation. Vendor acknowledges that Owner may have one or
-----------
more third party vendors, contractors and other personnel engaged to provide
work, equipment or services to Owner in connection with or related to this
Contract. Vendor agrees to reasonably communicate and cooperate with such third
parties at all times and, at the request of Owner, coordinate Vendor's and
Vendor's Subcontractors' activities hereunder with the activities of such third
parties.

26.29 Survival. Notwithstanding any expiration or termination of
--------
this Contract, the provisions of Sections 2.8, 12, 13, 14, 15, 18, 20 and 26.18
shall continue in full force and effect. Any termination hereunder shall not
relieve Owner of any payment obligation accrued prior to such termination.

[***]

2.8.1 Call Forwarding. The [*] Product supports call forwarding as defined in
[*]. Call forwarding automatically forwards a call to another number. The types
of call forwarding to be supported are listed below.

2.8.1.1 Unconditional call forwarding (CFU). The [*] Product supports
unconditional call forwarding. If the mobile subscriber has activated
the unconditional call forwarding feature, all terminating calls to
this subscriber will be immediately forwarded by the MSC to the
subscriber's forward to number.

2.8.1.2 Conditional call forwarding on MS busy (CFB). The [*] Product supports
conditional call forwarding when the MS is busy. If the mobile
subscriber has activated the call forwarding busy feature, all
terminating calls to this subscriber will be forwarded by the MSC to
the subscriber's "forward to" number, if the subscriber is busy.

2.8.1.2.1 Conditional call forwarding on no answer or not reachable (CFNA). The
[*] Product supports conditional call forwarding on no answer, or if
the mobile is otherwise inaccessible, due to:

. mobile does not respond to a paging request

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

2.8.1.10 Message Waiting Notification. The [*] Product supports the ability to
illuminate a message waiting indicator on the mobile when unheard
messages are available in a voice mail system. Every time a change to
the message count is reported by the voice mail system, this is
conveyed to the mobile either when idle or active on a traffic channel.
When the count is greater than zero, a message waiting icon will be
illuminated on the subscriber's mobile. This feature typically uses
ANSI 41 MWN interaction between the MSC and HLR.

2.8.1.11 Voice Mail Notification via SMS. Voice Mail Notification (VMN) is
supported via SMS per [*]. The Mobile Station is notified whenever a
new voice mail message is received, and the number of unheard messages
will be provided for display on the Mobile Station.

2.8.1.12 Do Not Disturb. The Do Not Disturb (DND) feature allows a subscriber
to bar incoming voice calls, but it still allows the user to originate
calls and receive mobile terminated SMS, fax and data calls. The barred
voice calls are routed to voice mail or given other secondary call
treatment. The user can activate and deactivate DND by using feature
codes. The MSC typically obtains authorization by sending an IS-41
message to the HLR and sends the appropriate tone (confirmation or
deny) to the subscriber and releases the call.

2.10.2 Terrestrial Facility Management. The [*] Product supports Terrestrial
Facility Management. This is the management of terrestrial resources shared
between the MSC and the BSS. [***]

2.11 Security. The [*] Product supports the following security mechanisms.

2.11.1 Authentication. The [*] Product supports authentication. The purpose of
authentication is to prevent fraudulent mobiles that are produced by capturing
valid Mobile Identification Number (MIN) and Electronic Serial Number (ESN)
combinations from the air and programming them in another mobile (i.e. creating
a clone). Authentication is a method of verifying the authenticity of a mobile
station and denying service to invalid mobiles and thereby deterring fraud.

The authentication procedure can be used either as an autonomous procedure or
combined with other procedures such as:

. Registration

. Call establishment

. Network initiated authentication

The following authentication-related procedures are supported:

. Global authentication - a process in which the mobile station is required
to send the result of the authentication algorithm for verification by the
AC before every registration, call origination, and call termination

. Unique challenge authentication - a process in which the AC forces a
specific MS on the traffic channel to perform authentication. The unique
challenge authentication happens automatically after an SSD Update, and it
can be configured to occur every [*] call or turned off completely.

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

. SSD Update - The AC can initiate updating the SSD in the MS. [***]

. RAND management - The BTS is responsible for the RAND management which
involves generating and updating the RAND. The BTS regularly updates the RAND
after a configurable amount of time [*].

. Call History Count - The MS and AC each have counters that are simultaneously
incremented for each mobile originated or terminated call. The counters can be
compared during authentication, and if there is a mismatch, then the MS can be
suspected to be fraudulent. This is used when it is suspected that all the
parameters have been cloned.

[***]

2.12 Additional Functionality

[***]

Dual Tone Multi Frequency (DTMF) Signaling over [*]. [***]

The [*] Product supports out of band over-the-air processing of DTMF tones on
the reverse link. The BSC receives the TIA/EIA/IS-95-A DTMF messages, and the
BSC generates the appropriate DTMF tones to be sent over the PSTN.

The [*] Product supports out of band over-the-air processing of DTMF tones on
the forward link. The CMS [*] System Product sends the IS-95-A DTMF burst
messages.

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

Over the Air Activation Service Provisioning. Over-the-air Service Provisioning
(OTASP) enables automatic activation and service provisioning of wireless
subscriber units by downloading and uploading system parameters to and from the
wireless handsets. This service makes use of a network element called "OTAF"
(Over the Air Function) which acts as an activation function mainly responsible
for forwarding OTASP messages to and from the mobile handsets. [***]

Lawful Authorized Intercept (CALEA). The [*] BSS supports the requirements
specified in [*]. The interception and monitoring is for both call content and
call-identifying information. [***]

Pre-Paid Phone Service. The [*] Product supports the requirements specified in
[*].

2.13 Intelligent Network Service Functionality

2.13.1 Originating Trigger (WIN Phase I). The [*] Product supports originating
triggers. The trigger is implemented by the standard ANSI-41-D protocol to
provide enhanced services even when roaming.

2.13.2 Local number portability - [*]. The [*] Product supports the Local Number
Portability (LNP) Service [*]. LNP [*] enables wireless service providers to
operate in areas where wireline companies offer LNP for Wireline customers. LNP
[*] lets wireline subscribers keep the same telephone number when they change
from one wireline service provider to another. To determine if a particular DN
has been ported, industry-wide databases containing both wireless and wireline,
maintain the list of all the ported numbers and their new locations. These
databases are referred to as Number Portability Databases (NPDB). In the MSC,
blocks of portable DN number ranges are defined. If the dialed number is within
one of these number ranges, a query is launched to the NPDB to find out if the
number is ported, and, if so, to what new location is it ported. This applies to
all mobile originated calls and incoming calls.

2.13.3 Voice mail retrieval while roaming. The [*] Product supports voice mail
retrieval while roaming. With this feature, roaming subscribers can retrieve
their voice mail by dialing a short feature code, and the feature code is sent
to the subscriber's HLR for proper translation. The serving

[*] Certain material (indicated by an asterisk) has been omitted from this
document pursuant to a request for confidential treatment. The omitted material
has been filed separately with the Securities and Exchange Commission.

MSC can then route the subscriber based on the routing information supplied by
the HLR. This feature is dependent upon the system configuration and the
interconnection agreements.

2.13.4 Wireless Number Portability. The Product will support wireless number
portability [*].
